To all whom it may concern:

Be it known that I, LE G. STRANSKY, a citizen of the United States, residing at Pukwana, in the county'of Ernie and State of South Dakota, have invented certain new and useful Improvements in .Vaporizing Attachments, of which the following is a specification.

This invention relates to a vaporizing attachment for use in connection with motor vehicles, more particularly to animproved arrangement for cars of the Buick and Nash type, over the form of vaporizing attachment disclosed in Letters Patent #1,474,450, granted me November 20, 1923, but it is to be understood that a vaporizing attachment in accordance with this invention can be employed for any purposes wherein it is found applicable, and the invention has for its object to provide, in a manner as hereinafter set forth, a vaporizing attachment connected directly to and opening into the intake manifold of the engine and communieating by a conducting pipe with the vacuum tank or the fuel supply system and provided with valvular means for controlling supply of atmospheric air into the intake manifold on the suction stroke of the engine, without interfering with the feed of gasoline to the carburetor, and further to provide for the admixing of atmospheric air with to thoroughly vaporize the asoline supplied from the carburetor into t e intake manifold to produce an unusually rich and powerful charge whereby the eliiciency of the engine will be increased without increasing the cost of operation.

Further objects of the invention are to provide a vaporizing attachment, which is simple in its construction and arrangement, strong, durable, compact, thoroughly efiiclent in its use, readily installed and comparatively inexpensive.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodi ment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is an elevation of a-vaporizing attachment in accordance with this inven tion, showing the adaptation thereof in connection with a vacuum tank of a fuel supply system and the intake manifold of an engine.

Figure 2 is a front elevation of the attachment.

Figure 3 is a rear elevation of the attachment.

Figure 4iis a vertical sectional View of the attachment.

Figure 5 is a section on line 5-5, Figure 2.

Referring to the drawings in detail, 1 denotes the vacuum tank of a "fuel supply system, 2 an intake manifold of the engine, 3 a suction pipe leading from the vacuum tank to a vaporizing attachment in accordance with this invention, referred to generally by the reference character 4 and which is connected to and communicates with the intake manifold 2.

A vaporizing attachment 4, in accordance with this invention, comprises a cylindrical body portion 5, which is hollow and of substantial length. One end of the body portion 5 is closed, as at 6, and its other end is also closed as at 7, and which has depending therefrom, a cylindrical extension 8, formed with peripheral threads 9. The extension 8 is hollow and opens into the body portion 5. The lower end of the extension 8 is provided with diametrically opposed vertically extending notches 10.

Depending from the body portion 5, at.

a point inwardly with respect to the closed end, is a hollow extension 11, rovided with peripheral threads 12, and t e lower end of the extension 11 is formed with diametrically opposed notches 13. The extension 11 opens into the body portion 5.

The front of the body portion 5, centrally thereof, is formed with a rightangularly 'disposed hollow annular extension 14, provided with interior threads and said extension 14 opens into the body portion-5 and has connected therewith the lower end of the 'suction pipe 3, whereby communication is established betweenthe vaporizing attachment 4 andthe vacuum tank 1.

Depending from the body portion .4, centrally thereof, is a hollow extension 15,'whic h is greater length than the extension 8, or

the extension 11, and said extension 15, has its lower portion provided. with peripheral threads 16 and also formed with diametrica'lly opposed notches 17. The extension opens into the body portion 5.

Carried by and depending from the extension 11, is a cup-shaped member 18, having internal threads for engagement with the threads 12. of the extension 11. The bottom 19, of the member 18, is formed with a centrally disposed air inlet 20, and arranged within the member 18 is a globular valve 21, adapted to engage the lower end of the extension 11 for the purpose of partially closing the said lower end or for rer stricting thepassage' of air through said extension 11 to the body portion 5.

Mounted on the extension 15, as well as depending therefrom, is a cup-shaped mem ber 22, provided with internal threads for engagement with the peripheral threads 16 of the extension 15. The bottom 23 of the member 22 is formed with a centrally disposed air inlet 24, which is of less diameter than the inlet 20.' Arranged within the member 22 is a globular valve 25, adapted to seat against the lower end of the extension 15, for the purpose of partially closing the same, or for restricting the passage of air through the extension 15 to the body portion 5.

An elbow-shaped coupling 26 forms a part of the vaporizing attachment and ,is employed for connecting the attachment to the intake manifold 2, and one leg of the coupling 26 is formed with internal threads for engagement with the peripheral threads 9, of the extension 8. The coupling 26 depends from the extension 8 and has the lower leg thereof threadingly engaging with the intake manifold, whereby the attachment is set up 'to communicate with the manifold. Mounted in the lower leg of the coupling 26 and projecting into the intake manifold is a oraminous plpe 27 which is employed for breaking up the air as it is discharged into the intake manifold to assist in the vaporizing of the gasoline supplied from the carbureter.

The members 18 and 22 are milled, as at 28, to permit of the convenientmanipulation thereof by the fingers, or to provide for the grasping of the milled portions by means of a suitable tool. In operation, the suction on the tank 1 is bad through the pipe 3, extension 15, body portion 5, extension 8 and elbow couplin 26, but simultaneously with suction throng the parts mentioned, atmospheric air is had through the inlets} in the members 18 and 22, but during the suction stroke the valves seat against the extensions Band 15 and restrict the supply of atmospheric air. The air is sucked into the body portion 5 and discharged therefrom through the extension 8. The notches in the extensions 8 and 15 provide for the supply of atmospheric air to the intake when the valves are seated against the lower ends of the extensions 8 and 15, as is obvious. A reater supply of air is had through the mem er 18, as the inlet 20 thereof is larger than the inlet 2 l in the member 22.

The arrangement of the various elements is so set up as'to cause proper Working of the vacuum feed at all speeds of the engine.

The vaporizing attachment is especially adapted for the removal of carbon from within the engine and when such operation is desired, a cup is placed under the member 22, and after the engine has warmed up, open the throttle about half-way and then pour water into the cup. The water will be sucked into the engine and form steam in the cylinders and which loosens and removes the carbon, if this operation is repeated once a day for three days while the engine is warm. To facilitate the removal of the carbon, a substantial quantity of baking soda is added to the water in the proportion-of two heaping tablespoonfuls of baking soda to one quart of water. p

The attachment is so set up as to provide for the supply of atmospheric air to the intake manifold of the engine in a manner so as to prevent the breaking of the vacuum in the vacuum tank Where a little suction is necessary to draw the gasoline fromthe supply tank to the vacuum tank and the globular valves ofier a suflicient resistance to permit the engine to draw the proper amount of air out of the vacuum tank and gasoline from a supply tank or other source.

. The inner diameter of the extension 14 provides for a much larger passage than the passage formed by the extensions 11 and 15, since the greater amount of suction is had through the extension 14 from the vacuum tank 1, and this provision provides for a proper Working of the vacuiim feed during'all speeds of the engine.

From the foregoing description taken in connection with the accompanying drawings,

a vaporizing attachment is set up, whereby atmospheric air is supplied to the intake manifold of'the engine for the purpose set forth, during the suction stroke, andwithout impairing the vacuum in the fuel feed member having a lateral tubular extension intermediate its ends for connection to a conduit leading to the vacuum tank of an internal combustion engine, said member further provided with an inner and a pair of outer spaced depending tubular extensions, one outer and the inner extension having an air inlet, a valve therein for closing the inlet and means in connection with the valve to constitute a by-pass, an angleshaped coupling element connected to and depending from the other outer extension and formed of a vertical and a horizontal leg and with the horizontal leg threaded for connection directly to the intake manifold of the engine, and a foraminous pipe mounted within said horizontal leg and extending irpn said vertical leg into the intake mani- 2. An attachment for the purpose set forth comprising a combined air supply and conducting element in the form of a substantially short tubular member having a lateral tubular extension intermediate its ends and an inner and a pair of outer depending spaced tubular extensions, one outer and the inner extension communicating with the atmosphere and further provided with an air inlet, a valve for closing the inlet and means in connection with the valve to constitute a by-pass, an angle shaped coupling element connected to and depending from the other outer extension and formed of a vertical and a horizontal leg and with the horizontal leg threaded for direct connection to the intake manifold of an engine, a pipe leading from said lateral tubular extension to the vacuum tank of the engine, and a foraminous pipe mounted directly within said horizontal leg and of a length to extend therefrom into the intake manifold of the engine.
